What in the air causes you to have allergies?

The allergy antibody response is a key trigger of allergic reactions. Parental smoking increases the risk of their children illnesses like bronchitis, chronic cough and asthma.

Too many germs inside your house are also bad for your health and can lead to allergies.


What can an air purifier do?

Air purifiers force air through a special screen that traps particles including allergens like pollen, pet dander, and dust mites. They also capture irritant particles such as tobacco smoke.

The best-known mechanical filter is the high-efficiency particulate air (HEPA) filter ( developed during World War II to prevent radioactive particles from escaping from laboratories ).

Capacity and Clean Air Delivery Rate – The AC4825 is suitable for rooms up to 155 square feet of in size which makes it perfect for most bedrooms.

Ease of Use and Maintenance – All you need to do is wipe it down with a soft, dry cloth to prevent dust from collecting on the vents. The filters should be vacuumed once every two weeks on average and replaced every eight months.


Call me biased, but this is hands-down the best looking air cleaner I’ve come across. With its efficient 3-stage filtering system, this air cleaner will eradicate all pollutants found in the air inside your home. It’s quiet, easy to use and maintain and affordable as well

Indeed, both GermGuardian units, the Honewell HPA300  and Coway  AP-1512HH  had received 4.5 stars (out of 5 stars) and Honeywell 50250-S had received 4 stars.  There is a good chance that you would be quite  happy with any of these five products.


However, there are a couple important  differences that you may want to consider before  making up your mind:

  • GermGuardian air purifiers come with germ killing  UV-C filtering.best air purifier for allergies
  • ​GermGuardian have 4 stages of  filtering as opposed to two for  the Honewell units.
  • ​The product is lighter and therefore easier to move around.

  • Highly effective. This unis eliminates most of the contaminants in the air. Its 3-in-1 filter design enables it to remove particles, germs, and odor from the air.
  • Quiet operation. Although this unit produces some sound, it is tolerable and not disturbing. You can comfortably sleep with this unit running in your bedroom if you set it to low operation.


  • Unsuitable for large rooms. This system is ideal for small rooms only. Their air cleaning effectiveness is lower when the unit is employed in relatively large rooms.
  • Plastic smell. A good fraction of users have pointed out that the system produces an unpleasant “plastic” smell. Such users feel that a system designed to clean and freshen air should not be producing any smell.


In spite of its relatively small reach and the occasional plastic smell that one can feel in the early days of its uses, we are quite satisfied with our tests and recommend it. Best air purifier for allergies.

Can’t comment on the for life aspect but I bought this one 14 months ago and have had no problems leaving it on low 24/7. For $100 I am happy with it. And I should admit I have only replaced the filter once and it has still held up.
